This video is all about the programing instruction. Paulo integrates the Civil 3D API, Dynamo for AutoCAD and Civil 3D, with Dynamo core functionality to generate a result that cannot be accomplished without all the pieces working together.
This is an in-depth and instructive walkthrough of Paolo's Iron Python script code block with all the structures, mechanics, methods, and details.
Paolo's AKN page listed above includes other Dynamo for Civil related videos you will find instructive.
